the Cosmos

The near cosmos are dominated by five sister planes, disk-like masses of earth, slowly rotating through a complex pattern that casts them at periodic pseudo-phases and rare eclipses, so that they appear almost as moons from one another. These are further orbited by the plane Empyrean whose fiery halo is known as the Sun. In the age of portals, the inhabitants of the planes had frequent commerce, but thousands of years have passed since that time. Travel is almost unknown, although regions where small, isolated portals still exist can be found (especially in certain mountain ranges, ley lines playing a similar role in physical geography to real-world plate tectonics).

Algol is green in the skies, covered in jungles and seas. One face is dominated by the continent Sujavedra, where the war between the titans Levh and Tilia has eliminated human life from all but the most remote outbacks. The reverse face is an archipelago, vast to defy any summary.

Arioch, the red plane, is a harsh expanse of rusty gravel swept by acrid winds. During the age of portals, histories say, it was colonized by Carcosans, and their capitol on Arioch, Sytor Arra, was the center of a plane-spanning empire. In the upheaval that ended that time, the portals were torn down, and the colonists were trapped on Arioch, isolated from the other planes.

Astrologers debate whether Carcosa is properly a plane or should be termed a hell. Ruled in eons past by serpent men, gray-skinned space aliens, or even more bizarre, forgotten immensities, Carcosa is now inhabited by the fallout and jetsam of these societies and their cryptic experiments.

Empyrean’s environment is deadly to most mortals, so its geography is little known. Great mages are said at one time to have had the power to withstand the heat and to have visited a gargantuan metropolis there, built of brass and ruled by Imix, an esper of elemental fire.

Enoch, a cold, forested plane, is the most human inhabited of this cluster. It is the home plane of this campaign, and its [[geography?]] is described in more detail elsewhere.

Ioun’s two faces are a stark contrast: one a bright, silvery white, and the other a dark, charcoal gray. Viewed from Enoch, it makes a full rotation every month. It’s said that exposure to the bright face of Ioun has a baleful influence on men’s personalities, and the dark face has no gravity so only insects can survive there. Neither face has ever been permanently settled by intelligent creatures.
